ROASTER.

Specification of Letters Patent.

Patented Nov. 2.0, 19,06.

Application filed March Z7, 1906. Serial No. 308.320.

To @ZZ whom, t may concern:

Beit known that I, EVERETT T. SHORTT, a

I citizen of the United States, residing at St.

Louis, State of Missouri, have invented certain new and useful Improvements in Roasters, of which the following is a specification. invention relates to roasters for coffee, cocoa-beans, peanuts, and other substances; and its primary object is to provide a novel and highly-useful device of this character wherein provision is made for examining the substances at any time during` the roasting process and without stopping the rotation of the roasting-cylind er and one wherein the roasting-cylinder is formed with frusto-conical ends terminating in tubular trunnions providing means for journalingthe roastingcylinder within a suitable casing, means for the application of the testing device, and means for the reception of a crank-handle, said testing device and crank-handle serving to close the open ends of the roasting-cylinder.

.A further object of the invention is to pros vide a roaster wherein the roasting-cylinder is'formed with a corrugated sheet-metal lining havingl its transverse ends turned up to provide ways for the reception of the ends of a slidin section of the lining.

A stil further obj ect of the invention is to provide a roaster which can be applied to any construction of heating apparatus, one which is simple and durable, one by means of which substances such as coffee, cocoabeans, andthe like may be roasted without the loss of their aroma, and one which may be manufactured and sold at a comparatively low cost.

With the above and other objects in view the invention consists of the construction, combination, and arrangement of parts hereinafter fully described, claimed, and illustrated in the accompanying drawings, where- 111- Figure 1 is a view in front elevation of a roaster constructed in accordance with my invention.= Fig. 2 is a central vertical sectional view thereof. Fig. 3 is a sectional view on the line 3 3 of Fig. 1. Fig. 4 is a detail view in elevation of the roasting-cylinder, the closure therefor being partially removed. u Fig. 5 is a detail perspective view of the testing device, and Fig. 6 is a view in elevation of a fragmentary portion of one end of the cylinder.

Referring to the drawings by referenceenumerals, 1 designates a casing having its up; per end fully open and provided with inturned flanges 2. The bottom of the casing is centrally depressed, as at 3, and provided with'an opening 3a. The cover 4 is secured to the casing by means of hinges 5 and is locked in closed position thereon by means of a hook-plate 6 and button 7, secured, re# spectively, to the cover 4 and casingl. Those portions of the hinges 5 which `aresecured to the casing 1 are formed withfledg'es 8, adapted to support the cover 4 in open po-v sition. The cover 4 is provided with a suitable handle 9, by means of which the same. may be opened or closed and by meansof which the device may be transported'. i AThe upper side edges of the casing 1 are provided with semicircular recesses 10, while the lower sid'e edges of the cover 4 are provided with semicircular recesses 11, said recesses being alined to provide bearings for journaling the roasting-cylinder 12 within the casing. Secured to the sides of the casing 1 are reinforcing plates or strips 13, having their upper ends recessed and alined with the recesses 10, whereby the sides of the casing 1 are strengthened to form a proper support for the roast-` ing-cylinder 12. i

The roasting-cylinder 12 is provided witha corrugated sheet-metal'lining 12a`and with frusto-conical ends 14, terminating in tubu? lar trunnions 15, said trunnions being dis-l posed within the bearings formed by the re-` cesses 10 and 11. The cylinder 12 and lining 12a are provided with longitudinally-,extending openings 16, through which the silb-v stances may be placed within and removed from the cylinder. The edges 1 7 of the lining 12a are turned upwardly', as at 18, to pro'- vide ways for the reception of the ends of a sliding section 19 of the lining 12a, said'section being secured to the cylinder-cover 19a, which is provided with a suitable handle 20, by means of which it may be readily and quickly applied and removed. The cover 19a has its ends offset to engage under the edges of the cylinder 12. cylinder 12 is cut away to correspond to the transverse contour of the section 19 to permit the cover and section to be removed. As the cylinder-linin is formed from corrugated sheet metal, t e lips 21 thereof will suitably agitate the substance during the rotation of the cylinder to prevent burning.

The testing device comprises a channeled portion 22 and a handle portion 23. The

One end of the IOO ics

IIO

channeled portion 22 is adapted to be placed within one of the tubular trunnions 15, so as to dispose the greater portion thereof within the cylinder 12. The handle portion 23 serves to limit the inward movement of the channeled portion 22 and also serves .to close this end of the cylinder. When it is desired to -examine the substances, the channeled portion 22 is turned upward, so as to receive a portion thereof during its agitation, and then the testing device is removed by means of the handle 23. After the testing device has been replaced the same may be inverted, so as to prevent any of the substance accumulating therein to insure the uniform roasting of the substance.

The cylinder is removed by means of a 4crank-handle 24, said handle being provided with an annular stud 25, frictionally engaging in the other trunnion 15, which closes this end of the cylinder 12.

The formation of the cylinder 12 with the frusto-conical ends terminating in tubular trunnions 15 not only providesmeans for journaling the cylinder, means for the reception of the testing device, and means for the application of the crank-handle, but also adapts the cylinder for use as a canister, which may be, after the coffee has been roasted, placed so as to deposit thecoffee within a grinding-mill, thereby obviating the necessity of removing the coffee first from the cylinder and feeding it to a grinding-mill.

The roaster is adapted for application to any construction of heating apparatus, and to partially illustrate its adaptability I have illustrated it in Fig. 1 of the drawings as being positioned upon a small gasolene-stove. This stove consists of a base 26, from which rise vertical standards 27, said standards 27 being adapted to support the roaster above a burner 28.

From the foregoing description, taken in connection with the accompanying draw' ings, the construction and mode of operation of the invention will be understood without a further extended description.

Changes in the form, proportions, and minor details of construction may be made within the scope of the invention without departing from the spirit or sacrificing any of the advantages thereof.

Having fully described and illustrated my invention, what I claim is v 1. A roaster comprising a casing, a roasting-cylinder journaled within the casing and provided with a corrugated sheet-metal lining, said cylinder and lining being provided with openings, said lining having'its edges turned up to provide ways, and a cover for the roasting-cylinder, said cover being provided with a corrugated sheet-metal lining having its edges slidably mounted in said ways.

2. A roaster comprising a casing, a roasting-cylinder journaledwithin the casing and provided with a corrugated sheet-metal lining, said cylinder and lining being provided with openings, said lining having its edges turned up to provide ways, and a cover for the roasting-cylinder having its ends offset to engage under the edges of the cylinder, said cover being provided with a corrugated sheet-metal lining having its edges slidably mounted in said ways.

3. A roaster comprising a casing, a roasting-cylinder provided with frusto-conical ends terminating in tubular trunnions and with a corrugated Vsheet-metal lining, said cylinder and lining being provided with openings, said lining having its edges turned up to provide ways, a cover for the roasting-cylinder, said cover being provided with a corrugated sheet-metal lining having its edges slidably mounted-in said ways, a testing device fitting within one of said trunnions, and a crank-handle having a stud fitting within one of said trunnions.

In testimony whereof l afliX my signature in presence of two witnesses.
